[engine][directx]Fixes #120: Wrong u,v coordinates were given, because of int/int division rounding.
u,v coordinates need be calculated in floating point division.
[engine]Refactor IND_Input render dependency injection. Dependency is assigned after correct initialization.
[engine]Fixes #119 by setting mouse coordinates on window creation to center.

That way no weird behaviours occur when opening in windowed mode and mouse position ends outside the window.
